My feeling is that some of what you are alluding to might be covered by UDDI,
however as is happening in an instance of SOA deployment that I am involved
in - UDDI by itself is not going to be sufficient to express all the metadata
that is needed for a client to successfully and contextually interpret all
that a Web Service does.
My attempted solution is to capture this additional metadata by leveraging
central metadata services of my enterprise. I guess what I am saying is that
the concept of "central metadata" might be a valid candidate as a component of
the Reference Architecture we are considering.
Since I was unable to participate in the F2F, (due to some last minute
commitments that I got called into), if this topic was discussed, please
accept my apologies for bringing it up again.
Thanks!

Subject: RE: [soa-rm] Re: Autonomous Services?
Folks - -
On my way home from N'awlins Wed night, I had a thought on this
discussion.
I think we expect services in an SOA to be independent of the kind of
shared contextual knowledge we usually presume within a local computing
environment. We expect that the requesting service will be able to
obtain all the info it needs to use the responding service successfully
by processing the responding service's description metadata. I do think
this is a core characteristic of SOA services.
I'm not suggesting we reinstate the use of the word "autonomous" as a
handle for this concept since it demonstrably caused confusion at the
f2f. If we need a handle, perhaps "self-sufficient" or
"self-documenting" or "introspective" (naaah - forget that one.)

We discussed and the submitter withdrew the submission pending
clarification on exactly what is meant by Autonomous nature WRT
services. It may be re-submitted and probably will however we do not
have consensus on it at present.
